Description

Technical Field

[0001] The utility model belongs to the technical field of cooling fans, and in particular relates to a cooling fan which uses ice water as a cooling medium. Background Art

[0002] The cooling fan uses a circulating water pump to continuously pump out the water in the water tank and sprays it evenly on the evaporative filter layer through the water distribution system. The outdoor hot air enters the evaporative cooling medium, fully exchanges heat with the water in the evaporative cooling medium, and the cool and clean air that is cooled by evaporation and heat absorption is pressurized by the low-noise fan and sent into the room, so that the hot air in the room is discharged to the outside, thereby achieving the purpose of cooling the room.

[0003] Currently, cooling fans also bring moisture into the environment when blowing cold air, increasing the ambient humidity and reducing the user's physical comfort. Utility Model Content

[0004] The utility model aims to solve the above-mentioned problems and provides a cooling fan which uses ice water as a refrigerant.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solution: a cooling fan using ice water as a refrigerant, comprising:

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 The utility model provides a technical solution: a cooling fan using ice water as a refrigerant, comprising:

[0022] A cooling chamber 1 is a sealed box disposed in a machine body 2, and the cooling chamber 1 is filled with a coolant. An air inlet 3 and an air outlet 4 are disposed on the machine body 2;

[0023] A plurality of cooling air ducts 5 passing through the cooling chamber 1, and two ends of the cooling air ducts 5 are respectively connected to the air inlet 3 and the air outlet 4;

[0024] An air intake fan 6, which is installed on the air intake port 3;

[0025] The interior of the cooling air duct 5 is a Tesla valve structure, so that the hot air entering the cooling air duct 5 generates a vortex, so that the air is fully stirred, the contact area with the cold wall of the cooling air duct 5 is increased, the flow rate is appropriately slowed down, and the heat exchange is maximized to achieve a cooling effect;

[0026] The outer wall of the cooling chamber 1 is made of heat-insulating material to minimize the loss of cold in the cooling chamber 1;

[0027] The air outlet 4 is provided with a deflector 7 which guides the air outlet direction of the air outlet 4, thereby improving the use effect of the cooling fan.

[0028] Working principle: First, the coolant can be cold water, and the cooling chamber 1 reduces the temperature in the cooling duct 5. Secondly, the intake fan 6 runs to draw hot air from the air inlet 3 into the cooling duct 5 for heat exchange. The interior of the cooling duct 5 is a Tesla valve structure, so that the hot air entering the cooling duct 5 can generate a vortex, so that the air is fully stirred, and the contact area with the cold wall of the cooling duct 5 is increased, the flow rate is appropriately slowed down, and the heat exchange is maximized to achieve a cooling effect. Finally, cold air is blown out from the air outlet 4, and the deflector 7 has a deflecting effect on the cold air to achieve a local cooling effect. During the cooling process, the air is not in direct contact with the coolant in the cooling chamber 1, and the ambient humidity will not increase, which greatly improves the user's physical comfort.
